Claims. (01. 72-128) This invention relates to the class of tools'and more particularly to a mortar spreader for use in constructing walls of hollow-cementitious building blocks.

- An object of this invention isthe provision of a mortar spreader which will enable the application-of mortar in a convenient and rapid manner to a hollow building block so that the mortar will not fall into the air spaces or hollow portions of the building block when being applied thereto in the erection of a. building wall, partition wall, or like structure.

Another object of the invention is the provision of a mortar spreader which is capable of adjustment so that it may be used with varying sized hollow blocks when constructing a masonry wand Still another obiect'of the invention resides in the provision of laterally adjustable arch handle posts which arch handle posts provide means for retaining mortar that is positioned between adjacent building blocks in the same course of building blocks. 1

Still another object of the invention resides in the provision of U-shaped channel plates for reception of a slide to which there is attached suitable mortar retaining means for retaining the mortar which is positioned between adjacent building blocks in the same course of blocks.

Still another object of this invention resides in the provision of detachably mounting extension legs for the mortar spreader which maybe used for preventing mortar from oozing between adjacent building blocks.

Still another object of this invention resides in the provision of the bevelled surfaces on this mortar spreader which enable the various functions of the device to be accomplished with a 2.

Figure 5 is a vertical'sectio'nal detail as taken along the plane of line 5-5 as in Figure 4;

Figure 6 is a sectional detail of an alternate form of securing the central spine member and minimum of eifort and which also enables the device to be readily removed from engagement with the building blocks on which it is used.

Still further objects of the invention reside in' the provision of a mortar spreader that is strong, durable, highly eificient in operation, simple in construction and manufacture, capable of being readily applied to various sized building blocks having various size cores, and which mortar spreader. may I be inexpensively produced.

These, together with the various ancillary ob- 'jects of the invention which will'become apparent adjustably'securing the arch handle post to the central spline member;

Figure 8 is an exploded perspective detail showing the construction of the slide and the mortar retaining means which are slidably mounted relative to the side frame members of the invention; and

Figure 9 is a perspective detail showing the construction of extension legs which are adapted to be'detachably secured to the arch handle posts.

With continuing reference to the accompanying drawings, wherein like reference numerals designate similar parts throughout the various views, reference numeral l0 generally designates a wall formed from hollow building blocks having cores 12 which extend vertically through the building blocks.

The device comprising the present invention, which is generally indicated by reference numeral [4, is adapted to provide means for preventing mortar from falling into the cores l2- and to provide'means for preventing mortar from oozing from between the mortar joints .formed between adjacent hollow building blocks. in the same course.' d

The mortar spreader I4 includes a central spine member 16 which is longitudinally extending and which has secured thereto core covers [8. The core covers [8 are, in fact, secured to parallel upwardly extending flanges 20 between which the spine member I6 is received, and bolts 22 are used to detachably secure the covers to the spine member.

I Secured to the side faces of the spine member [6 are attaching plates 24 to which there are attached cross bars 26 which are T-shaped in cross-section. Each of the cross bars 26 is provided with a plurality of slots 28 therein through which bolts 30 extend, which bolts are threadedly engaged in plates 32 secured at-the upper ends of arch handle posts 34 which are substantially Z-shaped and T-sha'ped in cross-section. Terminally secured between arch handle posts 34 are side frame members 36. To the side frame members there are attached triangular shaped flanges 38 which form an important element of the invention in that they permit ready removal of the'mortar spreader from the wall being constructed and also enable a trapezoidal shapedmortar deposit, as indicated at 40, to be readily emplaced on one of the blocks comprising the wall. To enable the ready removal and easy replacement of the mortar spreader on the wall to be constructed, the arch handle posts have their lowermost portions provided with an outwardly" extending flange or bevel 42.

Slidab'ly engaged in the side frame members- 35 are slides 44 which have secured thereto legs 46 which are provided with oifset portions 58 to maintain mortar from oozing, therebetween,,

especially when hollow cores for the blocks are mutually formed by the adjacent ends. of the. adjacent blocks.

As indicated, in! Figure.- 9, there are: provided extensions for the arch; handle pos s, enerally" designated by reference numeral 52,. which have. slots. 54 therein for reception of the flanges 42 at the bottonr of'the arch handle posts 34;. Eun ther, the extensions 52 areprovided; with apertu-res 5.6; through which. suitable bolts. may be passed for. securing the extensions. to; the arch handle posts through which suitable apertures. 5& have. been formed; These extensions arelprovided with flanges 69* similar to the" flanges 42 so that the device may be: readily removed and easily emplaced on. the wall with. the extensions: 52; thereto. attached.

Referring now to. Figures. 4;- and 5,, it will. be. seen that another form of the invention. comiprises the concept of providing a. central spine member, as indicated by reference. numeral 62 which is adapted to: be positioned between. the; upwardly extending flanges of. angle iron members 84 which are.- secured. to the core covers; 65, Itv is. to be, noted that; the angle iron membars 6&- are offset. from the longitudinal axis of. the core covers Eli. in order thatthe core. covers. may be; readily interchangeable and yetrpermit; the reinforcing rods to pass through. apertures, as. indicated at. 5.8 in the. core. cavers... These reinforcing, rodsv may be positioned in: the corestB when it isdesired to fill selected cores so. as. to reinforce. the entire wall structure.

. Referringnow to Figures 6' and. 7,. it will be. seen that there. is; shown. another form. or man.- ner of securing, the arch handle. posts 34[ to. the. cross-bars, which, in this form of the invention, are preferably of U-shape; in cross-section and are indicated by reference numeral 10. The 7 cores. are provided with; transverse slots 12 through which bolts. M. extend, the. bolts. I4 being secured in. plates 18 which, are attached to the arch handle posts 34, Nuts 18,- are. provided for securing the arch handle posts relative to the cross-bars Hl after the device has been ad: .iusted to the. proper-size,

Since; fromthe foregoing, the construction and advantages of, this adjustable mortar spreader are readily, apparent, further description. is; believed to be-v unnecessary.

However, since.- numerous modifications will readily occur to those skilled in. the art, after a consideration of the foregoing specification and accompanying drawings, it is not intended to" limit the invention to the precise embodiment shown and described but all suitable modifications and equivalents may bereadily re.- sorted to which fall within the scope of. the. appended claims.
